Aerialist Nik Wallenda plans to cross the Grand Canyon in June on a tightrope 1,500 feet in the air, without a safety harness - a feat that will be televised live.
Wallenda said he would traverse a remote section of crimson-hued canyon owned by the Navajo Nation in what will be his first major stunt since he last year became the only person to walk a wire over the brink of Niagara Falls.
"This is another one of my dreams coming true," Wallenda, 34, told Reuters in a brief telephone interview. "This is one that has been on my bucket list for some time."
Wallenda, a seventh-generation member of the "Flying Wallendas" acrobat family, said the tightrope walk across the famed gorge is higher than he has ever before attempted. The walk, scheduled for June 23, will also be about 1,500 feet long.
He said the canyon crossing has been in the making since 2008, but he only recently received permission from the Navajo Nation.
